STAI R OARPET FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 426,661, dated April29, 1890.

Application filed July 27, 1889. Serial No. 318,899. (No model.)

. To all whom it may concern:

this specification.

This invention relates to certain improvements in that class ofstair-carpet buttons or fasteners illustrated in Patent No. 394,315, inwhich a triangular button is employed in connection with a nail or screwfor holding the stair-carpet in position.

The object of this invention is to secure a longer bearing on the carpetat the angle between the step and riser to hold the said carpet in saidangle more smoothlyand to reduce the cost of construction; and itconsists in the arrangements and combination of parts, substantially aswill be hereinafter set forth, and finally be embodied in the clauses ofthe claim.

Referring to the accompanying drawings, in which like letters indicatecorresponding parts in each of the figures, Figure 1 is a frontelevation of a portion of a stairway, showing the relation of thefastener to the carpet. Fig. 2 is a section of the same, takenvertically through the fastening-pin, dad, and Fig. 3 is an inside orback view of the fastener in detail.

In said drawings, a indicates the steps and risers forming the stairway,b the carpet arranged thereon, and c the fastener for holding the carpetin position in connection with or by means of the fastening screw or pin(1.

The said fastener consists of a body f, of wood or other suitablematerial, which is preferably triangular when viewed endwise or incross-section, as in Fig. 2, having two faces to press the carpetagainst the step and riser and into the angle formed by the same, and athird face on which the ornament is formed, the third face beingpreferably provided with a metallic facing or covering g, which is heldto said body by lugs g, which extend against the rear sides, as shown inFig. 3. To secure a longer bearing on the carpet than can beconveniently, economically, and effectively formed out of one piece ofmaterial, I have provided a rod 6, which extends longitudr nally throughsaid body, as indicated in Figs. 2 and 3, the ends of the rod projectingbeyond the ends of said body at the inner angle of the button an inch(more or less) at each end, so as to hold the carpet smoothly in placein the angle. The body of the button is longitudinally grooved, as at h,to receive the rod, and at the ends of said body are formed projectionsi 'i, which engage the rod and hold it in the groove. The said projec'tions are preferably formed integral with the covering. There the hole jfor the fasten ing-pin (l is formed the rod 6 is preferably bent out ofa straight course, as shown in Fig. 3, to allow for the proper passageof the said fastening-pin without perforating said rod; but said rod maybe perforated, and in that event the course of the rod will be straight.I

I am aware that modifications in the 0011* struction of the fastener maybe made with; out departing from the spirit and scope of this invention;but for convenience of manu= factnre, economy, and general efficiency Iprefer the specific construction above described.

WVhat I claim as new is- 1. The improved stair-button herein described,combining with a body fa rod e, which extends oppositely beyond the endsof said body, substantially as and for the pun poses set forth.

2. The improved stair button or fastener combining a body, a metalliccovering and rod, the covering having projections to hold the rod inproper longitudinal relation to the body, substantiallyas and for thepurposes set forth.

3. The improved stair-button combining with a grooved body having facescorresponding with the step and riser a rod secured in said groove andextending beyond the ends of said body, substantially as and for the purposes set forth.

I11 testimony that I claim the foregoing I have hereunto set my handthis 15th day of July, 1889.
